PAPER-Box.

SPECIFIGATION formng part of Letters Patent No. 508,570, dated November 14,1893.

Application filed February 13.1893- erial No. 462,048. (Na model.)

.each end an attached lining strip of thinner paper which is folded in to constitute the closure at the top and bottom of the box. In such a box as heretofore commonly constructed, the tube has been slitted or notched at the corners for some distance from each end and creased transversely between the slits to form fiaps which have to be turned inward at right angles in closing the ends of the box, and the lining strips are pasted or attached only to those parts of the interior of the tube beyond the corner slits or notches and transverse creases which form the fiaps, the so'attached lining strips being left free from or unattached to the fiaps so that they may be folded in before and independently of the fiaps, which latter are made deep or long enough to overlap each other over the folded-in lining strip.

According to my invention I paste or attach the lining strip not only to the parts of the tube beyond the corner slits or notches but also to theflaps and I make the fiaps so shallow or short and form them in such manner at the corners of the tube that they may, without overlapping each other, fold in with the lining strip and 'yet permit ,the 'lining strip to be folded in with as much facility as though it were free from them. By this construction I provide as good a closure for the ends of the box while I save stock in the fiaps and also greatly simplify the operation of closing the ends of the box and so save time .and labor in that operation.l

Figurel is a perspective view; Fig. 2 a ver- .tical or longitudinal section and Fig. 3 an end view of a box embodying my invention, Fig.

1 showing the bottom closedl and the top partly closed, Fig. 2 showing the bottom closed and the top open and Fig. 3 showing the top or upper end closed.

. A is the body of the box consisting of apaper tube of rectangular transverse section having both its ends notched at the corners as shown in the upper end at a a in Fig. 1, and having its sides creased in transverse lines b b between the notches aa to form fiaps c c c c which may be folded over, as indicated by the front flap c in Fig. 1 and as shown in Fig. 3 and at the bottom of Fig. 2, the notches a a being of such form that the edges of the adj acent flaps may come together or nearly together as shown in Fig. 1, or at least that they do not overlap.

B B are the lining strips consisting each of a strip of paper of such thickness as to permit it to be easily folded, of such length that it may surround the interior of the box and of such width or depth that one of its longi-V tudinal margins may be pasted to andjaround that portion of the interior of the body of the box just within or beyond the creases b b which are made for the fiaps, and that its outer edgemay project beyond the said creases so far that it will fold in sufiioiently far over the cavity of the box to make a good closure. The width or depth of the pasted margins of the strips B B within the body of the box is indicated between the creases b b and the lines d d which represent the inner edges of the strips. The said stripsB B not only have their inner margins pasted to the interior of the box but they are also pasted to the fiaps, so that when the said strips are folded in, the fiaps turn in with them and make substantial corners all around the end of the box.

Either or both ends of the box may be constructed as above described, but in explaiuing``V the filling and closing of 'the box I will assume that both ends are so constructed. For filling such a box it is first held in any suitable manner while the lining strips are folded in 'from the four sides in succession according to the us'ual way of folding in such lining strips, as shown in Figs. 2 and 3, the fiaps turning in with and over the folds of the lining strip. The last two folds e e of the lining are gummed or pasted at their tips or edges to make them adhere to the folds previously turned in and the bottom is thus completed. -The box is set up on its closed end IOO tached to the interior of the body portion and to the interior of said flaps whereby the flaps will be turned inward With and by the folding Iiln of the lining strip,substantially as set fort JOHN J; HO'FFMAN.
